AbstractObjective:Juvenile nasopharyngeal angiofibroma may be successfully resected using endoscopic techniques. However, the use of coblation technology for such resection has not been described. This study aimed to document cases of Fisch class I juvenile nasopharyngeal angiofibroma with limited nasopharyngeal and nasal cavity extension, which were completely resected using an endoscopic coblation technique.Methods:We retrospectively studied 23 patients with juvenile nasopharyngeal angiofibroma who underwent resection with either traditional endoscopic instruments (n = 12) or coblation (n = 11). Intra-operative blood loss and overall operative time were recorded.Results:The mean tumour resection time for coblation and traditional endoscopic instruments was 87 and 136 minutes, respectively (t = 9.962, p < 0.001). Mean intra-operative blood loss was 121 and 420 ml, respectively (t = 28.944, p < 0.001), a significant difference. Both techniques achieved complete tumour resection with minimal damage to adjacent tissues, and no recurrence in any patient.Conclusion:Coblation successfully achieves transnasal endoscopic resection of juvenile nasopharyngeal angiofibroma (Fisch class I), with good surgical margins and minimal blood loss.

Objective: Endoscopic excision of juvenile nasopharyngeal angiofibroma (JNA) was carried out with the objective of minimizing blood loss and attempting to complete excision of tumor under direct vision with the help of Hopkins telescope.Study design: A retrospective 12 year study of 6 cases of JNA treated by endoscopic excision is presented.Result: According to Radkowski’s classification, two patients were stage Ia, two were stage Ib and two patients were stage IIb. The mean duration of the surgery was 2 hours. The mean intra-operative blood loss was 575 ml. The mean follow –up after the primary operation was 23.3 months. All the patients but one were free of disease. One patient had a recurrence in the pterygopalatine fossa requiring a successful revision procedure 3 years after the primary surgery.Conclusion: Endoscopic resection of JNA is a difficult but effective operation in experienced hands. The endoscopic management had less intra operative blood loss, lower occurrence of complications, shorter length of hospital stays and lower rate of recurrence. So it should be considered as a first choice option.Birdem Med J 2014; 4(2): 74-78

Abstract Background Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign, but the locally aggressive, vascular tumor that occurs almost exclusively in young men. Although this tumor accounts for only about 0.5% of head and neck tumors, it is by far the most common benign nasopharyngeal neoplasm. It is presented typically with epistaxis, obstructive symptoms, and chronic otomastoiditis. The examination of this tumor reveals pale reddish-blue mass. The tumor is seen on imaging as vividly augmenting soft-tissue mass centered on the sphenopalatine foramen. The treatment of choice is usually surgical resection; either open or endoscopic. Pre-operative embolization is usually done to help with hemostasis. We aim to address the efficiency and the safety of endovascular modality in JNA. Methods In the period between January 2012 to December 2017, 20 male patients with age ranging from 6 to 20 years were referred to the Endovascular Unit, at Departments of Neurosurgery in Sohag, Alexandria, and Tanta University Hospitals with JNF. Preoperative trans-arterial embolization was done, followed by endoscopic surgical resection by our ENT surgeons. All patients were subjected to clinical and radiological Imaging evaluation pre embolization, post embolization, and post endoscopic resection. All patients had clinical and radiological follow-ups for at least 1 year. Results 20 male patients with JNA underwent preoperative super-selective trans-arterial embolization. The average age at presentation was 13 years. All patients underwent successful embolization with total obliteration of vascular blush of the tumor in 15 patients, and near-total obliteration of blush in 5 patients. The dramatic effect of preoperative embolization was observed on limiting intraoperative blood loss (average 200 ml) and decreasing the time of surgery (average 2.5 h). There was no permanent morbidity or mortality related to either embolization or endoscopic resection in all patients. Conclusions Trans-arterial embolization is strongly recommended in patients with JNA, it offers a good assist to the surgeon, reduces blood loss, decreases the amount of transfusion, improves the degree of resection, reduces operative time, and decreases the incidence of recurrence.

Abstract Objective The Aim of the study is to compare between transverse and longitudinal uterine incision in abdominal myomectomy regarding intraoperative blood loss Design: A randomized Controlled interventional study. Setting Ain Shams Maternity teaching hospital. Patients and methods 52 patients undergoing abdominal myomectomy for single myoma were involved The patients were randomized into two groups that showed no significant difference in demographic data, characters of myoma or indication of surgery Results Our results proved that there was no significant difference between both incisions regarding intra-operative blood loss, need for blood transfusion, post-operative Hgb drop, operative time or incidence of postoperative fever. Conclusion Transverse uterine incision for myomectomy does not cause more blood loss than longitudinal incision. There is no difference between both incisions in operative time or postoperative complications Trial identifier: NCT03009812, MY-789

Intraoperative Bleeding

Resection of a juvenile nasopharyngeal angiofibroma (JNA) is challenging because of high intraoperative blood loss secondary to the tumor's well-developed vascularity. Endoscopic sinus and skull base surgeons commonly collaborate with neurointerventionalists to embolize these tumors before resection in an attempt to reduce the vascular supply and intraoperative bleeding. However, angioembolization can be associated with significant complications. Geometric alopecia from angioembolization of JNA has not been previously reported in the otolaryngologic literature. In this study, we discuss geometric alopecia from radiation exposure during preoperative angioembolization of a JNA.
